Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material:040802#

TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: Sample dried at 105°C and sieved < 125µm
Contact with:
powdered cellulose
Key result
Sample tested:
other: 2:1 sample to cellulose ratio (w/w)
Parameter:
preliminary test
Remarks on result:
slow smouldering
Remarks:
Burning did not propagate. Localised smouldering was sustained for 330s after the ignition source was removed
Sample tested:
other: 2:1 barium nitrate to cellulose ratio
Parameter:
preliminary test
Result:
32 s
Remarks on result:
vigorous reaction in the preliminary test
Remarks:
sample completely finished burning at 48 s

The test material/cellulose (2:1) reaction is moderate, with no burning time noted: The burning did not propagate down the test item/cellulose cone. The test item blackened when in contact with the ignition source.

Interpretation of results:
GHS criteria not met
Conclusions:
the substance should be classed as "not an oxidising solid"
Executive summary:

The oxidizing properties were determined in accordance with the EU A.12 test guideline and using a butane micro torch as a source of ignition in a preliminary test. In this test, the mixture of test item/cellulose (ratio 2:1) was compared to a reference/cellulose (same ratio) which vigorously reacted in 32s. With the test item/cellulose mixture, burning did not propagate. The substance should be classed as “not on oxidizing solid”.

Description of key information

The substance should be classed as "not an oxidising solid"

Key value for chemical safety assessment

Oxidising properties:
non oxidising
